Nokia, now lightened of its handset load thanks to Microsoft, has made an acquisition to expand its HERE mapping business, one of the assets that has remained with the Finnish company.

It has bought Desti, a mapping startup and app maker that uses artificial intelligence and natural language processing to help people find what they are looking for. Desti is a spin-out from SRI International, the same group that produced Siri, now part of Apple.

As part of the deal, the existing Desti app will be shut down. Don Zereski, VP of search and discovery at HERE, says it will be wound down “within the next 90 days.” The iOS app has already been pulled from the App Store.
